Y This invention relates to improvements in shuttles and, moreparticularly, yto shuttles used-for weaving tape and other .narrowfabrics, and being an improvement upon the shuttle shown in ourjpendinglapplication for. patent bearing Serial lNumber 672,472, tiled November3,1923;Patent `No.1,5.99,287.

yThe object oi this invention is, more particularly, to secure a moreetectiventakeup dev-ice and a suitable tensioii-device to cooperategwththe same. f -1 jeo lVith such objects in view, our inventio consists inthe construction'and combination of parts l as hereinafter described andclaimed. v i

F igs. 6, 7 8 .and 9-show in detail the parts tensioning Vwhich serve asthe mountings for the vseveral members of vsaid tensioning and take'lthere is a toothedrackS., as appears in Figs.

1 and 2. The surmounti-ng lenticular plate is shown at l9; and the twosides of thev arch rising from plate 9 are shown at 12 and 13, *thelatter being hinged to the plate l9 and Y 13 and the -former being splitat 17, with a notched-latching-pin 16011 the upper'half vengagedby aspring-pin 15-on the lowerV half.

Alenticular vplate above the bobbin is f shown at 49 in Figs. 1, 2, 3and 9.v In Vthe present case, the plate 49 extends through the archlmember 13 and is attached tothe bottom V0i" 1511.6 upper half by screws,as at 13a and t0 thejlOwerhalt of arch member 13 by bracket 13b andscrews 13C; while the opposite end of the plate 49 is secured to thebottom of the upper half of arch ineinber 12 by t-he aforesaid saidlatch-pin 16.

The bobbin 14 Vstands between the two plates Y9 and 49, having a socketwhich fits overv a shortstud .onthe plate 9 and issecuredtheretobyaninternal spring-latch 18. In our present invention the tensioning andtake-up apparatus is mounted on `the upper` lenticular plate 49 bymean'sof` a' bridge-plate 50, shown separately. in Fig. 8,

"v ivhich isot' an inverted V fornnwith its re' sp'ective ends securedto theshort bent-up as Ia support foranangle lever pivotally arrangedthereon' `by means of the pin 53 .fitting into aperture 530i' saidplate. Said l plate 50` is also provided Withan aperture 54 throughwhich the-.thread T passes upwardly' from the bobbin 14.` A-tensionispring 61 is securedat one end to a lug 55 V,bent lup from thebridge-plate; 50 and at its i.

Thus, as the thread T emerges upward from hole 54,- it passes betweenvplate 56 and the in the overlapping part of plate 56.(KThis imposes a'drager tension on the thread according tov the `tension given to thespring 61.
